Hi, so for now, I am doing a simulation of a car contacting some types of barriers. Now I want to get the value of Impulse of the car, how do I extract this info from LS Dyna? Thank you.

Hi @yoshimori3456,

So you should be able to extract the motion (displacement, velocity, or acceleration) using the Post -> History tab of LS-Prepost and just select a node on the vehicle frame. There are generally 4 hard points used to track vehicle motion in an impact. Let me know if you want more guidance on this.

If you are using a model that was already made, there might be a *Database_History_Node that was defined on the vehicle that you can plot from the ASCII file or binout file.
